HARROW.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed May 8, 1907. Serial No; 372,495.

To all whom it may concern:

Be. it known that I, NICHOLAS A. SEIPEL, a citizen of the United States,and a resident of Healdsburg, county of Sonoma, State of California,have made certain new and useful Improvements in Harrows, of which thefollowing is a specification in such full and clear terms as will enablethose skilled in the art to construct and use the same.

This invention relates to harrows used for cultivating ground that hasbeen plowed, and one of its objects is to construct such a harrow as maybe used for tearing out the weeds between rows of vines or plants thedistance of which rows is not the same in every case. For this purposethe harrow is made adjustable.

Another object of the invention is to make such a harrow as will besuitable for working between rows where there is a deep furrow betweenthe several rows, as in the cultivation of rhubarb or asparagus.

Another object of the invention is to make such a harrow as may be usedas a rigid harrow, or which may be used as a flexible harrow at will.

Other objects of the invention will appear as the description of theinvention proceeds.

In the drawing, in which like numerals of reference refer to like partsthroughout, the single figure is a perspective view of the harrowlooking from front to the rear diagonally.

The harrow is provided with a center rail 1 made of angle iron, whichhas its front end upturned as at 2 to provide means to which to hitchthe team. The rail 1 is provided on each side with a plate having a pairof eyes 3 to which the rails 5 and 5 are secured, said rails beingcapable of a hinge like movement at the eyes 3. These rails 5 extendoutwardly to the rear and carry the teeth of the harrow, said teethbeing of any desired form. At the rear end of the rail 1 is a plate 4having an eyehole in each end, and bolted to the top of the rail 1. Thiseyeplate has a bar 7 run through each eye and extending outwardly to theside rail 5 nearest the center rail 1. The bar 7 is secured to this rail5 by means of the clamp 14, and this clamp 14 also holds a short bar 8in place said bar being alined with the bar 7 and being secured at itsouter end to the outer bar 5. Both sides of the harrow are built in thesame manner there being two of the bars 5 011 each side of the centerrail 1.

The handles 9 are secured to the center rail 1 by means of a clamp 10 attheir'lower ends, and by means of a pair of bars 11 which extend up to apoint near the top of the handles, said bars 11 being joined at theirlower ends and being secured to the plate 4 by the same clamp that holdsit in its position on the center rail 1. Now it will be observed thatthis construction is such as to leave the side rails 5 hinged tothe'center rail 1 in such a way as to allow them to be moved nearer toor farther from the handles. When the ground is in such condition'as torequire it the harrow may be left flexible as described above, but it isoften necessary to use means to hold it rigid. This means is the rod 13which is secured at its lower end to the outside rail 5 at a pointconsiderable distance from the center rail 1. The upper end of this rodis turned down in order that it may be placed in one of the holes in theplate 12 secured to the handle on the outside of the same. There is arod 13 for each side of the harrow and likewise a plate 12 for eachhandle. It will be observed further that the outer rails 5 and the innerrails 5 are both adjustable, since by simply loosening the clamp 14 itis possible to move the rails closer together or farther apart as may bedesired.

If desirable the section on one side may be raised off the groundentirely and thus the work will be done by one side of the harrow alonepermitting the harrow to pass through very narrow rows. When rows thathave been hilled up very high are sought to be cultivated all that isnecessary is to raise both sides of the harrow to the desired amount andthen a V shaped cutting surface will be presented to the ground, thusmaking it possible to tear the weeds out of a ditch like furrow withoutleveling the ground down in a way that is unsuited to the plants beingcultivated. If it is desired to work ground that is very rough anduneven it may be necessary to take the rods 13 out of the plates on thehandles and allow the sides to move up and down at will.

Modifications of the invention within the scope of the appended claimsare reserved.

Having thus described my invention in such full and clear terms as willenable those skilled in the art to which it appertains to construct anduse the same, what I claim as new and desire to secure by Letters Patentof the United States is as follows:

1. In a harrow, a central rail to which a team may he hitched, a pair 01toothed rails hinged at their ends to the ccnter rail and extendingoutwardly and rearwardly there from said hinges permitting said toothedrails to move either horizontally or vertically, means to adjust theoutermost rail with respect to the others, handles secured to the centerrail near its rear end, a plate having a series of holes carried by eachhandle, and a rod having a hook secured to each outer rail said hooksadapted to be placed in any one of the holes in the respective plates.

2. In a harrow, a center rail having downwardly extending; teeth and towhich a team may be hitched, a double eye plate carried by the centerrail on each side thereof near the front end of the same, toothed railshinged to the eyeplates and extending rearwardly and outwardly from thehinged rails horizontally with respect to the center rail, center rail,means to move the said hinged rails vertically and means to adjust theouter of the side rails with respect with respect to the center rail,and means to adjust said to the inner one. rails horizontally withrespect to the side center rail. In testimony whereof I have hereuntoset my hand this 5 3. In a harrow, a center rail having downwardlyextend 1st day of May at Healdsburg, CaL, in the presence of the 15 ingteeth, a double eyeplate carried by the center rail on two subscribingWitnesses.

each side thereof near its front end, toothed rails hinged NICHOLAS A.SEIPEL. to the eyeplates and extending outwardly and rearwardlyWitnesses: from the center rail, means to move said hinged rails ver-FRANI{ A. MADEIN,
